2 Claims. (Cl. 126-120) This invention relates to a chimneyless fireplace, and more particularly to a fireplace unit which can be used in apartment houses and any type of homes and buildings not equipped with a chimney.

Its principal object is to provide a chimneyless fireplace, which is compact and simple in construction, safe in use, and simple to use.

Another object of the invention is to provide a chimneyless fireplace construction, having dual conduits and means for creating a draft, filtering out combustion gases, smoke, etc., and discharging clean and non-harmful warm air into the room from both sides thereof.

Still another object of the invention is to provide a chimneyless fireplace having a novel arrangement and a construction, in which the filter compartments are removable so that the filtering members can be replaced from time to time.

Still another object of the invention is to provide a chimneyless fireplace composed of an inner section and an outer casing section, the operable parts of the device and conduits being located within said inner section.

Other objects of the invention will be apparent from the following description and drawings which illustrate a preferred embodiment of the invention.

In the drawing:

Fig. l is a front perspective view of the fireplace unit,

one of the filter compartments being shown removed from the unit;

Fig. 2 is a rear perspective view, showing the inner section separated from the outer casing section, a portion of the said outer casing being broken away for the convenience of illustration;

Fig. 3 is a sectional view on the line 3-3 of Fig.

Fig. 4 is a sectional view on the line 4--4 of Fig. 3; and

Fig. 5 is a sectional view on the line 5-5 of Fig. 1.

Referring to the drawings, the chimneyless fireplace comprises an inner section 10, and an outer casing section 11, the said sections being preferably made of light weight metal. The said two sections comprise the unit, and are clearly illustrated in separated position in Fig. 2 of the drawings.

Inner section is provided with a fire chamber or compartment 12, which as will be observed from Fig. l, is freely accessible from the front of the unit. Wood, coal or other solid fuel is burned in the said fire chamber.

Inner section 10 is also provided with a front wall 13 which surrounds the front open end of fire chamber 12. Narrower wall 13a is positioned on the rear face of said wall 13. Rearwardly extending from the top longitudinal edge of said wall 13a and integral therewith, and adjacent and spaced from the top and side edges of the said front wall 13 are the top wall 14 and its integral depending side walls 15. Spaced from and within said top wall 14 and side walls 15 are the walls 14a and 15a. Fire chamber or compartment 12 has a bottom wall 16, side walls 17, and an inclined top wall 18 and a rear wall 19. All of the said walls of the said fire chamber project beyond walls 13a, 14, 15, 14a and 15a. A depending rear wall 20 and integral side walls 21 close the space between the walls 13a, 14, 15, 14a and 15a forming the complementary combustion compartments or conduits A and B, as will now be more fully described.

As clearly shown in Fig. 3, upper wall 18 of fire chamber 12 is slotted at 22. Likewise wall 14a is similarly slotted at 22a, the said slots being in superposed alinement. A centrally located dividing plate 23 divides the spaces between walls 13, 13a, 14, 15, 14a, 15a, 20 and 21 into two complementary inverted L-shaped combustion compartments or conduits A and B. Each said conduit is square in cross-section, as shown in Figs. 4 and 5. Plate 23 depends from wall 14a and divides slots 22 and 22a into two parts. conduit A wil be identical with the description of conduit B, save that one conduit will be located on the left hand side of the unit, and the other conduit on the right hand side thereof. Conduits A and B are each provided with a plurality of vertically depending and spaced baflle plates 24 and 25 respectively and also with a plurality of upwardly extending and spaced baflle plates 24a and 25a respectively at the horizontal portions 26 and 27 thereof, respectively. Baifie plates 24 and 25 depend from top wall 14, and baffle plates 24a and 25a project upwardly from wall 14a.

The upper horizontal portion 26 of conduit A communicates with a depending vertical portion 28, and the upper horizontal portion 27 of conduit B likewise communicates with a depending vertical portion 29. There is located in each said vertical portions 28 and 29, a blower 30 and 31 respectively, adjacent the lower end thereof for creating a draft in conduits A and B. Positioned below each said blower is respectively a small filter compartment 32 and 33. As shown in Fig. 1, each said filter compartment 32 and 33 is removable through a rectangular opening on both sides in front Wall 13, adjacent the front side edges of fire chamber 12. There is located in each said compartment 32 and 33,

filter members F which are replaceable whenever de-' sired. The lower end of the vertical portions 28 and 29 of conduits A and B project laterally and each terminates in a square-shaped opening 34.

It will be noted from Fig. 2 that motors M are mounted on brackets BR on each side wall 17 of the fire chamber 12. The said motors M are electrically connected to drive the blowers 30 and 31. Fig. 4 shows the connection of one such motor M with the blower 31.

Outer casing section 11 comprises the top wall 35, side walls 36 and rear wall 37. The front of said section is completely open so that it can be readily assembled with inner section 10. An air vent 38 is provided in top wall 35. In addition, a grill 39 is provided at the lower corner of each side wall 36. As clearly shown in Fig. 3, each said grill 39 is provided with a plurality of vla nesi 40, the said vanes being difierently angularly incme For the assembly of inner section 10 with outer casing section 11, reference is made to Fig. 2. In the assembled position of Fig. 1, it will be observed that the top and bottom edges of front wall 13 of section 10 are contiguous with the free top and side edges of walls 35 and 36 of outer casing section 11. It will be further noted that each grill 39 is alined with each lower opening 34 of conduits A and B, and that save for front wall 13 inner section 10 is located wholly within outer casing section 11.

As shown in Figs. 1 and 2, the unit is provided with a switch 41, operatively connected, for varying the speed of blowers 30 and 31. The said switch is positioned on front wall 13 adjacent the top edge thereof.

The operation of the unit is as follows:

The fire is made in fire chamber 12, the solid fuel resting on bottom wall 16 of said fire chamber. The smoke, combustion gases, etc. are then drawn into conduits A and B through opening 22 in top wall 18, as shown by the large arrows. This is accomplished by turning on switch 41, and operating blowers 30 and 31 at the desired speed which creates a draft in each of said conduits. The smaller arrows show the path of travel of the smoke, combustion gases, etc. being drawn around bafile plates 24, 24a, 25 and 25a in the horizontal portions 26 and 27 of conduits A and B respectively. The bafiie plates serve to deflect and catch thereon fly ash, soot, etc.

The smoke and gases then pass into the vertical portions 28 and 29 of conduits A and B and through the filters F located in the filter compartments 32 and 33, where the gases, smoke, etc. are filtered out.

As shown in Fig. 3, the bottom wall of filter compartments 32 and 33 is provided with a plurality of Therefore, a description of spaced slats S, so that the filtered air can pass therethrough, into the lower parts of conduits A and B, and out of the unit through openings 34 and grills 39. There by, there is presented to the room hot or warm air, from which there has been removed the harmful and noxious gases, etc. The vanes 40 deflect the warm air at different angles into the room.

There has been illustrated and described a preferred embodiment of the invention, but it is obvious that numerous omissions, changes and additions may be made without departing from the spirit and scope of the invention. It is not desired to be limited to any specific arrangement of the various members that comprise the unit.
